array_replace_recursive
Replaces elements from passed arrays into the first array recursively

array...
array_replace_recursive replaces the values of the first
array with the same values from all the following
arrays. If a key from the first array exists in the second array, its value
will be replaced by the value from the second array. If the key exists in the
second array, and not the first, it will be created in the first array.
If a key only exists in the first array, it will be left as is.
If several arrays are passed for replacement, they will be processed
in order, the later array overwriting the previous values.
array_replace_recursive is recursive : it will recurse into
arrays and apply the same process to the inner value.
When the value in array is scalar, it will be replaced
by the value in array1, may it be scalar or array.
When the value in array and array1
are both arrays, array_replace_recursive will replace
their respective value recursively.
&reftitle.parameters;
array
The array in which elements are replaced.
array1
The array from which elements will be extracted.
&reftitle.returnvalues;
Returns an array, or &null; if an error occurs.
